Hello, I had a hard landing with my iris. It now is not working correctly. I am trying to find the iris troubleshooting guide mentioned in the manual. Can anyone point me in the right direction?
You need to be a member of diydrones to add comments!
My hard landings seem to throw the accelerometer off. I usually run through the accel/compas/radio calibration again to correct it. Make sure you do them in the proper order in Mission Planner.
My hard landings happen more than I prefer so I check the HUD and initial thrust/throttle before each flight....or else disaster awaits. I'll usually lightly throttle up to see if it takes off evenly. If one side rises I know there is a problem and I have to recalibrate.
My last tinkering session with the IRIS jostled the I2C compass receiver female connector. I had to use one of the other spare I2C ports and it works well now.
If a hard landing, or a crash throws the ACC of, its better to remove the upper bodyshell to check, if the PIXHAWK is still connected with all (!) damping foam parts. Furthermore its a great idea, to secure a component of the powermodule with epoxy glue like shown here, if its not secured already by 3DR.
Check that the arms and the motors are still mounted correctly. It sounds like the a motor or arm might be loose/ cracked. What is it doing when you try and fly it?

Thanks. It is currently listing to one side when it tries to take off. Is there a way to check the logs on the device.

Some other hints, which partly apply to the consumer version as well, here: http://www.rcgroups.com/forums/showthread.php?t=2046042&highlig...
